What does it mean to lock the focus?

Focus locking is a technology to adjust the lens distance through the camera to achieve clear shooting objects. Focus locking is an essential skill for scenes with unstable focus and cameras without autofocus. When the focal length is adjusted and the focus is locked, the camera focus will not be adjusted for the subject unless the focal length is adjusted or the focus is locked again.

In addition to locking the focus, you can also try to focus manually, that is, the photographer manually adjusts the lens to select the focus. In some scenes, manual focusing may be more stable and accurate than automatic focusing, and the depth of field can be controlled, making the captured image more layered and artistic.

Whether it is focus locking or manual focusing, it is a necessary skill for some skilled photographers. They can be used in photographers' daily shooting, and also become the common skills of professional photographers. However, whether it is focus lock or manual focus, it needs constant practice and practice to achieve the best shooting effect.
